Jakarta - Thick smoke caused by forest fires blanketing Indonesia's Riau province on Sumatra island forced the brief closure of the local airport on Tuesday, an official said.
Five flights were diverted to airports in neighboring provinces after the haze reduced visibility to below 1 kilometre on Tuesday morning, said Dedi Suryana, chief of the Sultan Syarif Kasim airport in Pekanbaru, the provincial capital.
"There were some delays in departures and arrivals but we have reopened now," he said.
